Oh my Word... Microsoft Office 365 unlatched after morning lockout

Five 9's

There nothing "enterprise" about choosing Microsoft. Still holds true. Five 9's, when dealing with Microsoft means price.

Can't even through money at a problem

The biggest downside to online/cloud apps and storage is when something goes wrong, you can't even throw money at the problem to get it fixed as fast as possible. Given that most major cloud services are several orders of magnitude larger than any of their clients, implementing a work-around to get you back up and running is not a priority. Ringing the on-call IT staffer and having them go fetch an offline back-up at 3am is part of their job and they should be able to guesstimate some sort of ETA.

Some stuff should be made offline

Office and productivity suite, for example.

Cloud is only relevant if/when you wish to collaborate with others online, or when you choose to autosave the progress of your work to the cloud, in addition to a local autosave.

Microsoft knows it can't churn out new boxes of WIndows and Office every few years anymore to rake in the money, so 'software as a service' is used as a method to milk you of your money through subscription fees.

Maybe Microsoft has been inspired by Adobe Creative Cloud.
